with a number of super osed guide tongues.-

Ordinarily, gauges 0 this type are provided. with a single guide tongue which is adapted to accommodate, well enough, stock up to a certain thickness, but by the prorisiou of a plurality of superposed tongues, as contemplated by the present invention, stock of any thickness may be accommodated merely by adjusting the proper tongue to operative position. Preferably two tongues are provided, since tliis number will ordinarily be sufficient. In the following description, I have set forth the invention as applied to a gauge having a prong adapted to engage the tympani sheet for retaining the gauge in position and while I shall describe and claim certain novel features in the manner of inormti ng thetonguesin such a gauge, it is to be understood that my broad invention is adapted to be applied to tympan gauges of all descriptions:

Referring to the drawings,

Figure 1 is a perspective View of a: embodying the present invention.

Figure 2. is a side elevation of thegauge, Figure 3 is a top plan View of the gauge, and a 1 Figure 4 is a bottom plan View of the same- Referring now to the drawings, 10 indicates a gauge body or frame composed of a gauge strip oi. suitable spring metal bent in sub stantially the shape of a rectangle. The

lilWUl" side 1E oft his rectangle is slotted as at and 13, Figures 1 and l, to form a prong 1 t adapted to be engaged in a tynipan sheet in the well-known nranner. The marginabportions of thelower side have scroll ends as at 15 and 16, sous to enable them to slide freely over the tynipan sheet in en' gaging thepronq. i a p The top side 11 oii the trame 10 has fingers 17 and '18 punched inwardly thereof,

these fingers being substantially T-shaped as shown, aligned, and extending in opposite directions, the head portions being apertured to receive freely therethrough the upper tongue 19. Tongue 19 is guided in slots formed in the endwallsQO and 21 of the gauge body adjacent the tops thereof, and somewhat below these slots the Walls are provided with similar slots adapted to receive and guide tongue 22, these tongues being substantially parallelfand in the vertical planes of the fingers. As maybe most PATENT orrice.

clearly seen from Figure 2, finger 17 is bent downwardly and then upwardly so that its free end engages the under surface of tongue 19, while finger 18 is bent downwardly so that its free end engages the top surface of tongue tongues with suflieientpressure to retain the latter, by frictional contact, in their ad jl isted positions. i

It will be obvious that the gaugiehas been illustrated in an exaggerated sizeytmd that in actual practice it will appronimutethe size of similar gaugesasnow on the market.

When thin stock is to be printed tonguefli will be adjusted to operative position but when stock of greater thickness than can be conveniently tahenfeareof by tonguefil isto' be printer, tongue 19 advaneedxflto operative position. By reason of this alternativenessof zrdjlust-f ment, thede vice, as shown, will befound to be a great convenience in shrubs Whereetock of considerable variation in thickness has to be printed; a i i the latter withdrawnland The ends of the lingers bear against the I h'ayeexplained above, however; the
